# SmithPlot Properties

Control appearance and behavior of Smith chart

Smith chart properties control the appearance and behavior of the Smith plot object. By changing property values, you can modify certain aspects of the Smith chart. To change the default properties use: .

s = smithplot(____,Name,Value)

To view all the properties of the Smith plot object use:

Clip data to outer circle, specified as 0 or 1.

Data Types: logical

Colors to use for multi-line plots, specified as three-column matrix of RGB triplets. Each row of the matrix defines one color in the color order.

For more information, see ColorOrder in the Axes Properties.

Data Types: double

Next color to use in color order, specified as a positive integer. New plots added to the axes use colors based on the current value of the color order index.

For more information, see ColorOrderIndex in the Axes Properties.

Data Types: double

Font name, specified as a character vector.

Note

• To display and print text properly, you must choose a font that your system supports. The default font depends on your operating system and locale.

• To use a fixed-width font that looks good in any locale, use FixedWidth. The fixed-width font relies on the root FixedWidthFontName property.

• The listfonts function generates list of available font names.

Data Types: char

Font size, specified as a positive integer.

Data Types: double

Font size mode, specified as 'auto'. Changes the font size based on window size.

Data Types: char

Background gird line color, specified as an RGB triplet, or as a character vector of color names, or 'none'. Using 'none' turns off the grid completely.

RGB triplets and hexadecimal color codes are useful for specifying custom colors.

• An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1]; for example, [0.4 0.6 0.7].

• A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Thus, the color codes '#FF8800', '#ff8800', '#F80', and '#f80' are equivalent.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Interpretation of bottom title characters, specified one of the following:

• 'tex' — Interpret using a subset of TeX markup

• 'latex' — Interpret using LaTeX markup

• 'none' — Display literal characters

#### TeX Markup

By default, MATLAB supports a subset of TeX markup. Use TeX markup to add superscripts and subscripts, modify the text type and color, and include special characters in the text.

This table lists the supported modifiers when the TickLabelInterpreter property is set to 'tex', which is the default value. Modifiers remain in effect until the end of the text, except for superscripts and subscripts which only modify the next character or the text within the curly braces {}.

ModifierDescriptionExample
^{ }Superscript'text^{superscript}'
_{ }Subscript'text_{subscript}'
\bfBold font'\bf text'
\itItalic font'\it text'
\slOblique font (rarely available)'\sl text'
\rmNormal font'\rm text'
\fontname{specifier}Set specifier as the name of a font family to change the font style. You can use this markup with other modifiers.'\fontname{Courier} text'

\color[rgb]{specifier}Set specifier as a three-element RGB triplet to change the font color.'\color[rgb]{0,0.5,0.5} text'

#### LaTeX Markup

To use LaTeX markup, set the TickLabelInterpreter property to 'latex'. The displayed text uses the default LaTeX font style. To change the font style, use LaTeX markup within the text.

The maximum size of the text that you can use with the LaTeX interpreter is 1200 characters. For multiline text, the maximum size reduces by about 10 characters per line.
